Burning
Invasive Juniper Trees Boosts Perennial Grass Recovery (Aug

Agricultural Research Service.ARS rangeland
scientists have figured out that cutting down invasive
juniper trees and burning them in the wintertime
not only reduces the wildfire risk from the dead
trees, but also helps keep invasive cheatgrass at
bay and helps native perennial plants to become re-established.

Invasive
Bullfrogs Done in by Flash Floods (Aug 13, 2010)Discovery News.
Scientists surveying native tree frogs and invasive bullfrogs in the mountain
oases for Mexico's Baja California found evidence that the bullfrogs are blindsided
by infrequent, powerful tropical cyclones that can occur. The native frogs are
adapted to avoid the violent flooding that ensues after torrential rains, and
stay hidden and dormant during the summer and fall, when hurricanes are likely
to strike. Bullfrogs live and breed at the same time the hurricanes are active,
which makes them more vulnerable when hurricanes cross the Baja Peninsula. The
results of the study mesh with areas what many biologists have been arguing for
other places in western North America, which suffer from invasive fish. The fish
thrive in areas with dams with a normal amount of water, but remove the dam or
release water in a way that mimics the extreme high and low flows of many western
rivers, and the invasives suffer while the native species gain ground. The study
is published in the October issue of Journal of Arid Environments.
